Ok, so I'm re thinking what little I know about these bearing systems. I just watched a you tube from Rockwell showing how their system works. I do have a zert on my spindles so I assume I have a posi lube system. According to the video, to repack the bearings on the hub you slowly squeeze grease into the system until you have clean grease exiting around the castle nut and everything should be good! ?? I could do that right where the boat sits with a pile of rags and a grease gun? I would check those rear seals to make sure they have not been leaking. This company, in the display they had, there was only a rear seal and then the cap with the rubber piece you can pop out to get to the zert. I'm sure the old school will be to tare it down...
